Problems solved by technology
However, the conventional method has a problem in that delay or jitter, which results from channel characteristics, makes it impossible to guarantee reliable quality of speech (QoS).
Such loss of audio and video data mainly occurs during transmission via wireless environments.
However, the conventional portable terminal has a limitation in that, although it can store either video and audio data to be transmitted to the partner's terminal or received from the partner's terminal, the portable terminal cannot store video and audio data from both sides of a video communication.
